Comments:Here are some details on today's flight. "Stancomb Outboard", which is a new OIB flight and consisted of 5 Icesat-2 tracks and two tracks along the ice tongue of the glacier. There was an incident with the aircraft behind us during the start of our taxi. You probably have a better understanding than I do, but from what I understand, their stairs blew back from our exhaust and ended up hitting one of their engine cowlings. Due to this incident, it sounds like we will be relegated to performing engine starts on Taxiway E (or perhaps another suitable location) for the remainder of our stay here. We also had an issue with the housekeeping system hygrometer popping it's circuit breaker. Initial look at the problem seems to indicate that the currently-installed system (1011C) draws more power than the predecessor systems (1011A and 1011B), but the circuit breaker was not properly sized up to accommodate the higher power draw. Other than that, the flight went very smooth. The aircraft and science instruments all performed well. I think the CBS folks got just about everything they wanted for media. ATM: 100% data collection, instruments are all working well, no issues MCoRDS: 100% data collection, instrument is working well, no issues Snow Radar: 100% data collection, instrument is working well, no issues Gravimeter: 100% data collection, instrument is working well, no issues Data: 100% data collection for KT-19, only significant issue being the aforementioned hygrometer issue

Mission: 
OIB
Mission Summary: 
Mission: Stancomb Outboard
Priority: High
 
This new flight is designed to provides radar and lidar data along ICESat-2 ground tracks, mostly offshore of the grounding line of the Stancomb-Wills Glacier. This region has not been sampled by OIB prior to 2018.
 
A steadily improving forecast for this region and the Filchner Ice Shelf, but not yet clear enough elsewhere, meant that we selected this mission in a region that OIB had never before surveyed. A ramp pass at 2000 ft AGL was collected prior to the initial transit. Our weather assessment was quite consistent with that which we observed, but with none of the expected fog on the tongue. Low clouds dissipated as we approached the Stancomb-Willis Glacier Tongue. We extended the initial along-flow line by several minutes, so that we could cross the downstreammost ICESat-2 track and then beyond that by 70 seconds for a more useful gravity cross-over. We observed exceptionally large freeboards of some rifts at the end of that along-flow line. Otherwise, the flight proceeded smoothly and all lines/tracks were surveyed successfully. Winds were exceptionally light and generally less than 5 knots. A video crew from CBS News joined our flight and conducted several interviews during the course of the flight. A preliminary schedule has their segment(s) airing sometime next week (TBD). All instruments reported excellent data collection. ATM further experimented with Headwall data collection and better refined their acquisition procedure for it. 100% all around.
